IMPROVEMENT 1N MACHINE FOR MAKING- SASH. v

, The Schedule referred to in these Letters Patent and making part ofthe same.

To all whomtt may concern.-

Be it known that I, SETH C. ELLIS, of Jersey City, in the county ofHudson, and State of New Jersey, have invented a new and usefulImprovement in Machines for 'Outting Check-Rails of Sashes of which thefollowing is a full, clear, and exact description, reference being badto the accompanying drawings, sheets 1 and 2, forming part of thisspecification, and in which- Figure 1 represents a side view, and Figure2 a plan of a machine constructed in accordance with my improvement.

Figures 3 and 4 represent front views in part of an upper and lowercheck-rail, as fitted to their respect: ive stiles, or to one of such,ofan upper andlower sash, in illustration of'the work'to be done by myimproved machine.

Figures 5 and 6,top and under views of such parts. Figure 7, a verticalsection through the lower checkrail, showing the upper one'iu-contactwith it,- and Figures 8 and 9, transverse sections through the tenonportion of the said check-rails as detached from their stiles. I.Similar letters of reference indicate corresponding parts. a

My invention consist in a certain combination and arrangement of partsor devices in a machine for cutting the check-rails of sashes to fitthem to their stiles, whereby the mortises are out" in the tcuons ofsaid rails at their opposite ends, and dovetails .formed therein, in asimple, expeditious, and accurate manner, and whereby the saws orcutters for thus preparing or forming the opposite end of the rails maybe arranged in close proximity to each other.

Referring, in the first instance, to sheet 2 of, the accompanyin gdrawings- A represents the check-rail of an'uppcr sash, and A thecheck-rail of a lower sash.

B and B are the stiles of said sashes, with which the check-railsinterlock on opposite sides, only one of such stilesto either check-railhere being shown.

Figures 3, 4, 5, 6, and 7, showtherelative arrange- 'ment of theseparts, and the mannerin which the same are fitted together, in respectto which not-hing ishcre claimed as new.

My improvement is not designed to form the ends.

of the stiles, nor in any way to prepare thennthe work on such beingdone by other mechanism; neither is it adapted to dress or prepare thecheck-rails any further than to out the mortises a a'- in their tenons bb, and to form the dovetails c and 0' in or to their ends, and to fitwhich the ends of 'the stiles are suitably-cut.

The tencns l) b are formed on the check-rails, at their opposite ends,before said rails are introduced to a the machine which embraces myimprovement.

In further preliminary explanation it should be observedthat while,owing to the relative arrangement of the two sashes, the tenous b oftbeupper checkrail A, have their mortises a on'the front or fair side ofthe sash, the tenons b have their mortises a on or over the putty sideof their sash-and that said mor- .tises are of different width, or atleast preferably so; also that the dovetails or bevels c of or to thetenons l) of the upper check-rail are on the outside of the mortises a,at opposite ends of said rail, while the two ends or tenons b of thelower check-rail A have their dovetails or bevels c on the inside of themortisesa'i This difi'erence in the arrangement of the mortises a a",and dovetails tor bevels c c, necessitates a difference inthearrangement of the devices for cutting or. forming the same, and thismy machine accomplishes, as will appear from the following descriptionof it, or of such parts as are necessary to explain how the work isdone.

Referring now more particularly to sheet 1 of the drawing- 7 0 is theframe of the machine, arranged to carry, at opposite ends and on reversesides of it, circular saws D D and DD, the same being arrangedin pairs,and which should be hung so as to have a drunken motion on cross-shaftsE E, that may have rotary motion communicated to them by any suitablemeans, to revolve either pair of saws as indicated by arrows in fig. 1.V

The saws D D on the one side of the machine are for operating on the topcheck-rail A, at its two ends successively, and the saws D D on theother side of the machine, for operating on the opposite ends of thrbottom check-rail A.

In their operation on said rails it is desirable that. the cuts shouldbe made from their more exposed sides to their less exposed ones, so asto leave no ragged edges when the sashes are put together.

The pair of saws at one end of the machine cuts the mortises a a anddovetails or bevels c e in the righthand tenons of the two rails, andthe other pair of saws, the mortises and dovetails in the left-handtenon thereof.

Each pair of saws on the same side of the machine have arranged infi-ont of or in between them, reversely set or inclining feed-boards orbed-pieces F, F and WE, the same inclining upward from the saws, and

slots and set-screws d to suit difierent widths of rail, and furnishedwith a stop, '0, at foot-,to arrest the feed of the rail at thefinishing of the mortise.

Said bed-pieces are also made adjustable up ordown by slots andset-screws f to suit different thicknesses of rail.

To cut the mortises a in the teuons of the upper rail A, said rail isfirst fed down the one inclined bedpiece 1 under guidance and regulationof. its strip G and stop 6 against the saw I), which cuts the mortise inthe one tenon, and then reversed, or the opposite end of the railexposed in like manner, down the reversely-incliued bed-piece F to theaction of the other saw D on the same side of the machine, which cutsthe mortise in the opposite end of the rail.

Alike operation, and by similar means, namely, bedp'reces F F, withtheir guides G and stops 0 and saws D D, is also pelformed on the lowercheck-rail A to cut the mortises a in it.

To dovetail or cut the bevels c c in the tenons of the rails, the latterare then transferred respectively to, and fed down or over upperbed-pieces H H H iii arranged over the bed-pieces F F F and F", set alsoto incline (but preferably at a different angle,) in reverse directionaway from the saws.

These upper bed -pieces are likewise provided with guiding-strips, I,adjustable byv slots and setscrews 1, to suit difl'erent width oftenons, and stops it to arrest the rails at the proper point in theirfeed.

The bed-pieces H H on the one side of the machine answer for cutting, bythe saws D D, bevels 0, on the opposite ends of the upper rails A, andto this end are set sloping in an upward direction, outwardly or awayfrom the guides I of said bed-pieces, in order to give the properdirection to said bevels, while the bed-pieces H H answer in like mannerin connection with the saws D D for the dovetails or bevels c in thetenons of the lower rail A, and are set inclining on their faces in areverse direction, or in a downward direction outwardly or away fi'omthe guides I of such bed-pieces H H.

By the angular set of the several upper and lower bed-pieces relativelyto the saws, each pair of the latter may be set comparatively closetogether, and the rails, in being slid down separately over them, meetwith no impediment either from the saws not operating thereon, or theirrespective bed-pieces, thus securing great compactness to the machine,while the work done is effected in a most expeditious and accuratemanner.

\Vhat is here claimed, and desired to be secured by Letters Patent, is

1. The arrangement, substantially as shown and described, of the saws DD or D D, and their respective lower bed-pieces F F or F 1 provided withsuitable guides and stop for operation, essentially as specified. V

2. The arrangement, herein described, relatively to the saws D D or D Dof the inclined bed-pieces H H or H H, provided with guides I, andoperating in the manner essentially as herein set forth.

3. The arrangement, relatively to each other, of the lower bed-pieces FI F F, with their guides and stops, the upper bed-pieces H H H H, withtheir guides and stops, and the saws D D D D, substantially as shown anddescribed, and for the purpose or purposes herein set forth.

SETH C. ELLIS.
